More hyperelastic models for rubber-like materials: consistent tangent operators and comparative study

open access: yesJournal of the Mechanical Behavior of Materials, 2013
Rubber-like materials can deform largely and nonlinearly upon loading, and they return to the initial configuration when the load is removed. Such rubber elasticity is achieved due to very flexible long-chain molecules and a three-dimensional network ...

Eight-chain and full-network models and their modified versions for rubber hyperelasticity: a comparative study

open access: yesJournal of the Mechanical Behavior of Materials, 2015
The eight-chain model, also known as Arruda-Boyce model, is widely used to capture the rate-independent hyperelastic response of rubber-like materials. The parameters of this model are physically based and explained from micromechanics of chain molecules.

Phenomenological modelling of viscoplasticity

open access: yesRevue de Physique Appliquée, 1988
The essentials of phenomenological modeling of metal deformation behavior at small strain are introduced together with companion experiments which are performed with servocontrolled testing machines and strain measurement on the specimen gage length. Systematic experimentation leads to the viscoplasticity theory based on overstress and its properties ...

LHC phenomenology of supersymmetric models beyond the MSSM [PDF]

open access: yesJ.Phys.Conf.Ser.259:012002,2010, 2010
We discuss various phenomenological aspects of supersymmetric models beyond the MSSM. A particular focus is on models which can correctly explain neutrino data and the possiblities of LHC to identify the underlying scenario.

A New Phenomenological Model to Predict Forming Limit Curves from Tensile Properties for Hot-Rolled Steel Sheets

open access: yesMetals
A phenomenological model for the prediction of the forming limit curve (FLC) based on basic mechanical properties through a uniaxial tensile test can tremendously shorten the design time of the forming process and reduce the measuring costs.

Phenomenological Inflationary Model in Supersymmetric Quantum Cosmology

open access: yesUniverse, 2022
We consider the effective evolution of a phenomenological model from FLRW supersymmetric quantum cosmology with a scalar field. The scalar field acts as a clock and inflaton.

Material Composition Gradient Controls the Autonomous Opening of Banksia Seed Pods in Fire‐Prone Habitats

open access: yesAdvanced Functional Materials, EarlyView.
The seed pod valves of Australian Banksia attenuata plants are not simply bi‐layers which bend when dry. These experiments and models reveal complex mechanics, which allow seed release only after several steps of seed pod opening. Stiffness gradients prevent delamination of the valves during loading, and a shape‐memory function protects the seeds ...

Scaling‐Up of Structural Superlubricity: Challenges and Opportunities

open access: yesAdvanced Functional Materials, EarlyView.
At increasing length‐scales, structural superlubricity (SSL) faces challenges from physical and chemical energy dissipation pathways. This study reviews recent experimental and theoretical progress on these challenges facing the scaling‐up of SSL, as well as perspectives on future directions for realizing and manipulating macroscale superlubricity ...

COSMIC ANTIMATTER: MODELS AND PHENOMENOLOGY [PDF]

open access: yesParticle Physics at the Year of Astronomy, 2010
The possibility of creation of cosmologically significant antimatter are analyzed in different scenarios of baryogenesis. It is argued that there may exist plenty of antimatter even in our Galaxy. Possible forms of antimatter objects and their observational signatures are discussed.
